The struggle to tame the Mourne Wall

Posted on July 7, 2010 @ 2:29 PM in Walking

Paul O’ Connor makes a second attempt at the famous Mourne Wall Walk. Having learnt some valuable lessons from an initial aborted effort, Paul takes on one of the greatest mountain walks in ireland covering 35km and 3000 metres of ascent.

A wise man once told me that the definition of failure isn’t to fall down; it is not to get back up again. I had waited eight long months to get back up again, a time stretching from August 23rd 2009 to 6:20am on Monday, May 3rd 2010 when I found myself at the foot of the Mourne Mountains and the start of my second attempt at the Mourne Wall Walk.

I suppose you could say that the previous attempt had not gone well…  you would be pretty correct in saying that it had ended in something of abject failure and quite a bit of misery. On that occasion, the Mournes had quite simply chewed us up and spat us out again. We were the proverbial lambs to the slaughter; badly prepared, totally lacking the requisite fitness and arrogantly believing that we could triumph over whatever Nature could throw at us including the forecasted stormy weather.

Those arrogant presumptions were given fuel as we started out from Carrick Little car-park heading towards glistening peaks which were bathing in the warmest of autumnal sunshine. The first part of that particular walk had seen the Mournes effortlessly lull us into a false sense of security, so much so that we’d even had an extended lunch break down by Silent Valley reservoir all the while untroubled by our lack of progress and completely oblivious to the ominous gathering of a melee of dark clouds overhead.

Not even the discovery by one member of the party that he had left half his water supply in the car boot failed to lighten the mood. In our minds, we were Kings of the Mountains and anything that they could throw at us.

The prevailing mood began to change as we struggled up one side of Slievenaglogh and back down the other and by the time we reached the foot of Slieve Muck, the dark clouds had dropped down out of the sky and were rushing and dancing over the ground all around us.

Slieve Muck itself quite simply broke our spirit; our overfilled back-packs combined with a complete lack of visibility meant that each and every step became a mammoth task. It was only due to a now gale force wind at our backs that we managed to get to the top of Muck at all. The scene at the top was akin to Armageddon as menacing black clouds danced impetuously across its flat summit only occasionally giving way to reveal a glimpse of a forlorn looking trig pillar which appeared to be crying out for rescue.

Things went from bad to worse on the crossing from Muck to Carn. The last of the daylight ebbed away and the storm continued to pick up bringing heavy showers of rain with it. Murphy’s Law then kicked in to dictate that the walk spiraled even more in the direction of disaster; the heel of my walking boot splitting open as I tripped over a muddy rock and ended up on my backside.


Camped out during the first attempt

Camped out during the first attempt

We spent a very uncomfortable night camped to one side of the wall taking whatever shelter we could from the raging storm, our tents fiercely battered by the winds and occasionally threatening to pull free from their stakes. The next morning saw the storm still raging leaving us with no option but to abandon the walk. We downheartedly descended off the mountains and spent the long and miserable walk back by road to the car-park at Carrick Little with the bitterest taste of failure in our mouths.

Failure…. Abject Failure! It didn’t sit well with me over the winter months. Spurred on by that failure, I took up jogging and spent much of the winter building up my fitness levels to tackle the Wall again when the weather got better and the days got longer. Several people accused me of succumbing to some kind of mountain-related madness and there was probably more than a bit of substance in those accusations.

And so, at 6:20 am on the morning of May 3rd, I found myself starting out again from Carrick Little car-park on the road to redemption.

This time I had packed light, a pair of Inov8 trail running shoes had been broken in on some shorter walks and on my back was a Camelbak Apline Explorer pack which has an integrated 3 litre hydration reservoir. Instead of doing the walk over two days and having to carry overnight gear, I decided to do it over one long day. The good people at Mapyx Quo had provided me with an electronic copy of the Mournes Maps and their software had proved invaluable in allowing me generate a very detailed route card to download to my GPS. What the route card showed was that the most difficult part of the walk was the initial section as far as Muck by which point almost 50% of the ascent would be complete over just 33% of the distance. Once more, Muck looked like being a focal point in the walk – after that, everything should be a lot simpler!

The walk itself is something of a classic, described by the author Paddy Dillon as ‘one of the greatest mountain walks in Ireland’ and it is hard to disagree with him. The walk covers close on 35 kilometres with a total ascent approaching 3000 metres and the route itself was followed as part of an organized walk which ran annually between 1957 and 1984 only to be cancelled as a result of its own popularity when fears were raised over erosion to the route due to the huge crowds participating.

The wall itself was built between 1904 and 1922 by the Belfast Water Commissioners to enclose the water catchments in the Mournes. Between Carn Mountain and Long Seefin where it is at its stoutest, you can’t help but be impressed by the wall and in awe of the huge effort that must have gone into building it.

There are a number of places from which to start the walk but I chose the car-park at Carrick Little. From there, a short walk along a track brings you to the wall itself which offers a sure guide almost to the summit of the mighty Slieve Binnian, halting only when it reaches the summit Tor where it is replaced for a stretch by a wire fence. With a height of 747 metres and a height-gain of around 580 metres from the car-park, Binnian represents the perfect pulse-raiser. The summit proper is atop the impressive Tor and you’ll need to grapple with some rock should you wish to reach it. At 7am, I had the summit all to myself but dwelt there just a short while to admire the magnificent views down onto Silent Valley below as well as North-West across to some of the mountains I would climb later in the day including Meelmore, Meelbeg and Loughshannagh.

The descent down Binnian is over some very steep ground and you need to take care to avoid the slabs immediately below the Summit Tor. The wall passes over the summit of Wee Binnian but this can be bypassed through the notch to the left. The minor summit of Moolieve is next before you lose all of the height you gained by following the wall down to the reservoir at Silent Valley. As I crossed the reservoir and glimpsed up at Slievenaglogh towering over the water, apprehension set in. The stretch from Silent Valley to the summit of Muck had proved troublesome on my last effort albeit in more difficult conditions.

On the far side of the reservoir, turn right at the shelter and follow a track uphill. At the bend, leave this track to follow a vague path uphill through some wet ground and thick vegetation. Cross the fence at the top of this path and follow it up to the wall. This section of the walk is particularly boggy but the wall avoids the worst of the bog by continuing uphill before taking a ninety degree right turn to head for the slopes of Slievenaglogh. Take it from me that you are best advised not to give into the temptation to take a short cut through the bog. The climb up Slievenaglogh is steep in places across some bouldery ground but with a bit of care, a decent path can be picked to the summit of the mountain at 445 metres which is marked by a summit cairn. From the cairn, the path across to Slieve Muck is clearly visible.

Cross the wall to descend Slievenaglogh over some more very steep ground. A track leads from the bottom of the mountain across Banns Road before veering away from the wall to pass through a gap in a subsidiary wall. Veer back towards the wall and follow it up the relentlessly steep and seemingly never-ending slopes of Slieve Muck. There are a couple of points where the ground becomes too steep even for the wall and it gives way to slabs. You will need to steer to the right of these sections.

It was towards the top of Muck that I felt the first slight twinges of cramp in my legs but these were eased somewhat when the steep slopes gave way to gentler ground leading to the trig pillar on the summit plateau. It was a huge relief to reach this point of the walk so early in the day and with already over half the total ascent done, I could now look forward to tackling the sections of the walk which were new to me in the knowledge that most of the hard work was now behind me.

The section from Muck along Carn, Loughshannagh, Meelbeg and Meelmore is relatively straightforward with the height gain and loss between each mountain being small compared with that between Binnian and Muck. What I hadn’t anticipated was the cramp in my legs that was to arrive sharply and sporadically throughout the rest of the walk particularly during the ascents. The stone lookout tower on the whale-back bulk of Slieve Meelmore is an obvious landmark but the actual summit is marked around 100 metres away by a stone cairn. What is very striking along the stretch from Meelbeg to Meelmore is just how steep the section of the wall running up Slieve Bearnagh is – it really looks a preposterous and impossible angle from certain viewpoints.

The best method of climbing Bearnagh is to keep well to the right of the wall where the incline is somewhat gentler before picking your way upwards. I had by now adapted a pretty erratic zig-zag style of walking uphill, taking four or five lateral steps for each step upwards. By the time I reached the top of Bearnagh, I had adapted something of a ‘Basil Fawlty’ style funny walk and with quite a few people picnicking at the base of Bearnagh’s impressive summit Tor, I decided it would be best not to make an exhibit of myself by attempting to scramble up the rocks to the summit proper.

The wall continues across Bearnagh via a couple of smaller Tors which can be bypassed over a distinct path before dropping down to Hare’s gap. The gap was a hive of activity with people of various nationalities consulting maps and making plans for the day ahead. I on the other hand had the finish line in sight and only had eyes for the last stretch of mountains ahead running from Slievenaglogh across to Ulster’s highest point, Slieve Donard via Slieve Corragh and the mammoth bulk of Slieve Commedagh.

The steps leading from Hare’s Gap up the initial steep section at the foot of Slievenaglogh were sheer torture and I was glad when a man and his son stopped briefly to discuss the black clouds that were approaching as well as the man’s deep-held physicological fear of Slieve Bearnagh after he had come to an abrupt stop halfway up it’s relentless slopes on a previous assault. I was that busy concentrating on not blowing-up myself that I completely missed the ‘Diamond Rocks’, a crystalline outcrop of granite on the ascent to the summit cairn on Slievenaglogh. By the time I had crossed to the unassuming Slieve Corragh, I reckon I probably looked much like an unwanted extra out of a low-budget 1950’s war-film. Luckily this section of the wall doesn’t attract much walker traffic so my continuous utterances about ‘only 2 more left’ went unheard. The views from Corragh are arguably amongst the best along the walk with Slieve Bearnagh towering over the impressive Ben Crom Reservoir providing a spectacular backdrop.

It was on the ascent of Slieve Commedagh that the heavy black clouds finally made their move, streaming across Commedagh before depositing a heavy shower of hailstones over the mountain. Surely, only the mountains can delivery all four seasons within the space of a couple of hours. My pace of ascent had slowed to a crawl up Commedagh and the digits on my GPS counting down the distance to the summit seemed to be moving with the same lethargy as myself. I had now taken on a ‘boom and burst’ method of walking, pushing myself hard for 10 of 15 seconds before stopping for a prolonged rest and to let the now constant cramps in my legs abate. When the lookout tower finally emerged from the clouds at the summit of Commedagh, I only had one more mountain to climb, albeit the highest of the day.

I dropped out of the cloud down to the broad gap between Commedagh and Donard. Again, groups of people were gathered at the gap whilst others were at varying stages of ascending and descending both mountains, those close to the top visible only as tiny dots. Buoyed on by the sight of my last summit, I made good progress upwards stopping occasionally to speak to people taking the ‘tourist trail’ up the mountain including one man in his fifties who lived within sight of Donard but who had only climbed the mountain for the first time that afternoon. Pumped full of adrenaline and delight, he told me that he had proudly phoned his son in Australia from top of Donard to break the news to him. Slieve Donard was the first mountain I ever climbed and I had been taken by the impressive views both out to sea and across the rest of the Mournes. On a clear day, views reputedly stretch to the Wicklow Mountains as well as across to the Isle of Man.

If I had any feeling of completion when standing beside the huge cairn that marks the summit of Ulster’s at 850 metres, it was very much misplaced. I had not banked on the long and steep descent from the mountain down to and across the Bog of Donard and over to Long Seefin. This stretch of the wall seemed limitless, appearing to my tired mind and malfunctioning legs to stretch off into infinity. After what seemed like an eternity of walking combined with bits of sporadic running, I finally reached the curious little stone tower below Long Seefin at which point the wall loses its epic proportions.

A right turn at the strange tower takes you down the hill where you have a couple of options as to how to complete the walk. I opted to play fair and attempt to follow the course of the wall as closely as I could by following it down across the Annalong River and up the other side. This proved to be a bad choice; what looked like a short last stretch of the walk through Annalong Woods turned out to be something of a nightmare slog. The section of woods I passed through had been felled leaving thick grass and brambles which were knotted into the hidden remnants of the tree felling, all sitting atop uneven and boggy ground. The conditions underfoot and aching legs made for very slow and frustrating progress and it became very disconcerting on the couple of occassions that my legs stopped working completely. It was a feeling of immense relief that greeted the sight of the track leading back to the car-park at Carrick Little, so much so that I broke into a jog back to arrive at the car-park some 10 hours and 43 minutes after I had left.

The overriding feeling was one of relief, relief that I was finished, relief that I could sit down for a while and most of all relief that I had laid to rest the ghost of eight months previous. I had hoped to complete the walk in sub 10 hours but the struggle through Annalong Woods on exhausted legs had greatly eaten into my time. Along the 35km, I had fallen out with the wall on numerous occassions as it stood idly by watching dispassionately as I was seized by cramp and rendered immboile. At several stages, I had vowed never to visit it again but deep down I was full of admiration for it and knew that sooner rather than later I’d be back again walking alongside it. Most of all, I spent my time in a state of wonder and amazement at the amount of human effort, sweat and tears that must have been expended in building this amazing, unprobable and magnificent structure.

The walk really is a superb way to experience the Mourne range. The wall itself makes the mountians very accessible and navigation very easy. The circuit of the wall should not however be underestimated, the height gain and section as far as Slieve Muck in particular representing a very tough challenge which requires more than a decent level of fitness.

For me the main thing was not that I had fallen, it was that I had got back up again!

Please note: The popularity of the Mourne Wall challenge walk grew so much in the late 80's, early 90's that the route suffered from severe erosion and visitors to the Mournes were encouraged not to walk this route. Nowadays it is once again possible to roll back the years and walk this route in your own small groups (no more than 12 people). However, walkers are asked to be aware of and adhere to the principles of Leave No Trace. Visit for more information.

Great write up. Thanks for sharing.

What an excellent account. It makes my knees ache just sitting beside my laptop. Good luck for the next one!

An excellent account. Along with my brother, Norman, we did the walk on 7th June 1981. This was the Silver Jubilee of the YHANI Mourne Wall Walk and, I am glad to say, that at 79 I'm still walking.

Small groups of 12 in sufficient numbers lead to several thousand annually and great damage. Please do not encourage others to complete this route.

Great account and excellent photographs - I seldom see such clear weather in the Mournes.

I did the organised Mourne Wall Walk every year from 1971 - 1983 with a couple of solo ones since. It was a victim of its open success, the event you did in the 1970s to prove your fitness (compared to doing marathons in later years).

The traditional route started at Rourke's Park and used the road to Carrick Little CP. The route also came down to the road after Wee Binnian and went round the outside of the Silent Valley estate.

I shall have to have another go next year, age permitting, to celebrate my first round 40 years ago.

A fantastic account with great photographs! Having attempted (and failed!) the walk in the opposite direction only a week ago, I'm full of admiration...and a little envy. :)

I was part of the YHA organising committee for the Mourne Wall Walk in the 1980s. I have done the complete walk on two occasions, the second with my future wife in 1960. We fell out several times on the way round, but we still got married a year later. We now have 8 grandchildren and some of them are keen walkers. I still walk in the Mournes at least once a month at age 81.

You know your pictures just driving me crazy. Wow you guys just walked 35 Kilos with 2800 meters of Ascent , this is really encouraging.

The views from "Slieve Binnian" is just like a dream, really.

@Arthur Rodgers, your 79 and still walking? Really amazing. I really appreciate that. Even young guys like us do not walk, we sit in front of the laptop whole day long.

I decided to climb Slieve Donard for the first time on my 60th birthday (23/4/2011) accompanied by three of my children, my grandson and three other family members. My local pub landlord has now challenged me to do the Mourne Wall on my 61st!! Challenge laid down and accepted....this article has been really helpful starts tomorrow...

Posted by Robert Arthur Palin on May 29, 2011 @ 6:20 AM

I completed the Silver Jubilee walk in June 1981 and have my certificate to prove it. I remember the changeable weather,the Irish humour and the beautiful scenery, which included a very attractive female walker. I was ready to quit after 2 hours at the first refreshment break but spotted this lovely girl striding out and resolved to follow her for the rest of the day.During one icy downpour a group of Irish lads were huddled together for warmth crying out to passers by, "We are all going to die". A day I shall remember for the rest of my life.

At 77 I am still walking for an hour a day but on the flat I regret to say. Your photos brought back so many happy memories. Thank you.

Kind regards,

Bob Palin.

great advice! My wife and myself have practiced walking from carrick little to sleive binnian and over to sleive muck in order to expeience the mourne wall before we go 'hell for leather' and walk the whole route in one day. We have done 2 Belfast marathons and thought that was hard going!!! which us luck!

many thanks for your help.

Good photos that bring back fantastic memories. I did the walk in 1976 at age 16 (lied about my age). My two companions gave up at Hares Gap and got a helicopter ride back down and I nearly gave up with two mountains to go. A soldier in full combat gear (they used to have to do the walk as part of their training) stopped with me and encouraged me to go on. I did, thanks to who ever you are.

Posted by Ian Bailey on December 22, 2012 @ 9:25 AM

Great account Paul, in fact it was the best source of information for my attempts! I had similar experiences in my running attempts at the wall. Check out, - for the surrering

and... - for the redemption!

Happy reading!

First of all I want to say awesome blog! I had a quick question that I'd like to ask if you don't mind. I was interested to know how you center yourself and clear your thoughts prior to writing. I've had difficulty clearing my mind in getting my ideas out there. I do enjoy writing but it just seems like the first 10 to 15 minutes are usually lost simply just trying to figure out how to begin. Any suggestions or tips? Appreciate it! breast actives scam

Wish I knew the mournes as well as you do. Started climbing about five years ago. These mountains never cease to amaze me, love it. Just sorry I didn't start years ago. They have a very special place in my heart. I live in Ballymena and I can see the mournes from there on a good day.

Posted by Marc Le Baptiste on August 4, 2017 @ 10:55 AM

Great, great read. I'm a pretty much once a week regular to donard commedagh and chimney rock, and can even get through the bog of donard at chimney rock base with difficulty.

But where I'm really coming unstuck on doing part of this route is how to get from the wall across Annalong wood to carrick stuck for two hours on the side of Rocky Mountain, it was utter hell.

Posted by Ann Quigley on August 5, 2018 @ 9:02 AM

Hi Paul. Myself and my husband completed the walk yesterday in 16hrs finishing the last he in the dark.

A great achievement for us both given that we are both in our fifties. Majestic views and luckily our weather was perfect. And yes to say that we felt the challenge was almost complete as we stood on the top of Donard was also true of us. The descent and subsequent hike back to Carrick park was so deceptive. Very sore feet and aching limbs. Not for the faint hearted. And I don't intent in doing it again.

Howdy just wanted to give you a quick heads up and let you know a few of the images aren't loading correctly. I'm not sure why but I think its a linking issue. I've tried it in two different web browsers and both show the same outcome.
